Title: Verfahren und Schaltungsanordnung zur Anpassung der Zwischenkreisspannung an die Versorgungsspannung
Inventor: HUBER NORBERT
IPC: H02M5/458
Filed: 1998-12-08
Abstract: Sobald die Versorgungsspannung eines Spannungsversorgungsnetzes eine Höchstgrenze überschreitet, treten in herkömmlichen Umrichtern unzulässig große Ströme auf, die zur Zerstörung des Umrichters führen können. Die erfindungsgemäße Schaltungsanordnung zur Durchführung des erfindungsgemäßen Verfahrens ermöglicht den Betrieb eines Umrichters an einer in weiten Grenzen beliebigen Versorgungsspannung. Erfindungsgemäß wird zur Vermeidung von unzulässig hohen Strömen die Zwischenkreisgleichspannung des Umrichters immer so geregelt, daß diese über dem Spitzenwert der gleichgerichteten Versorgungsspannung U¶N¶ liegt. Dafür wird der Spitzenwert der gleichgerichteten Versorgungsspannung ermittelt und mit dem der Zwischenkreisgleichspannung verglichen. Ist die Zwischenkreisgleichspannung niedriger als der Spitzenwert der gleichgerichteten Versorgungsspannung, wird die Zwischenkreisgleichspannung über den ursprünglich eingestellten Sollwert hinaus angehoben. Dadurch wird verhindert, daß die Freilaufdioden zu unzulässigen Zeitpunkten leitend werden und einen zu großen Strom verursachen.

Title: Engine control and diagnosis system for motor vehicle internal combustion engine with exhaust gas recirculation
Inventor: ORZEL DANIEL V
IPC: F02M25/07
Filed: 1999-05-21
Abstract: The system has a number of sensors (18) for measuring engine operating parameters and an exhaust gas recirculation (EGR) valve (16) for permitting exhaust gas to flow from the exhaust system (14) to the engine (10) air inlet system (12). A controller (20) opens the EGR valve during a number of successive test periods during which it measures the engine speed response through the sensors. The test periods are separated by nonuniform intervals and the controller increases or decreases the intensity of the test periods in the event that the measured engine speed falls below or is greater than predetermined threshold levels. The controller measures the engine speed response to the opening of the EGR valve by observing the engine's speed change during a number of predetermined windows that correspond to the timing of the test periods and by comparing the observed engine speed change to a rolling average of the standard deviation of the engine speed. An Independent claim is included for a method for determining proper operation of an EGR system of an automotive engine that has an EGR valve operated by an engine controller.
